SPIKE FOR SHOES Filed AuE- 12, 1964 ATTORNEYS United States Patent3,195,246 SPIKE FUR SHGES Takeshi Ueda, 2-1 Izumi-cho, Isezalri, .iapanFiled Aug. 12, 1964, Ser. No. 389,092 1 Claim. (CI. 36-67) The presentinvention relates to a spike for shoes, and is more particularlydirected to a spike unit which is to be detachably attached to shoes,chiefly golf shoes.

According to the present invention, there is provided an improved spikefor shoes comprising a spike member which is made of an abrasionresisting steel and has at its middle portion a projecting rim and onthe periphery of its head portion an uneven surface, and a washer memberwhich is made of a light metal such as aluminum, aluminum alloy or thelike and has at its central portion an upwardly projecting cup tube openat its lower end and a downwardly projecting short tube, said twomembers being so combined that the washer member is mounted at its cuptube on the head portion of the spike member, the projecting rim of thespike member is firmly embraced by the short tube of the washer member,and by a roll pressing process applied to the outer surface of the cuptube a thread is formed on the periphery thereof and, at the same time,the inner surface of the cup tube is pressed into the uneven surface ofthe perpihcry of the head portion of the spike member.

In order that the invention may be clearly understood and readilycarried into effect, the same will now be explained more particularlywith reference to and by the aid of the accompanying drawings, wherein:

FIG. 1 is a perspective view of a spike according to the presentinvention.

FIG. 2 is a longitudinal sectional side view of the same.

FIG. 3 is a side elevational view of a spike member.

FIG. 4 is a sectional side view of a washer member before being combinedwith the spike member, and

FIG. 5 is a sectional side view showing the initial combination of thespike member and the washer member before completion of the spike.

Referring to the drawings, wherein like and corresponding parts aredesignated by similar reference characters, numeral 1 denotes a spikemember which is made of an abrasion resisting steel and applied with aheat treatment for increasing the hardness thereof, and the spike member1 is provided at the middle portion thereof with a projecting annularrim 2 and is threaded on the periphery of its head portion 3 to formthereon an uneven surface 4. Numeral 5 denotes a washer member made ofsuch a light metal such as aluminum, aluminum alloy or the like, and themember 5 has at its central portion an upwardly projecting cup 6 open atits lower end and also a short tube 7 projecting downwardly from thecircumference of the lower end opening of the cup 6.

For combining washer member 5 with the spike member 1, as shown in FIG.5, the cup 6 of the washer member 5 is put on the head portion 3 of thespike member 1, and the short tube 7 is curved inwardly to embrace theprojecting rim 2. Thereafter, the cup 6 is applied to thread rolls sothat by the roll pressing process, a thread 8 is formed on the peripheryof cup 6 and, at the same time, the inner bore surface of the cup tube 6is pressed into 3,395,246 Patented July 20, l9fi5 the uneven surface 4of the head portion 3 of the spike member 1 for being firmly andintegrally connected thereto. This spike is attached to shoes a by thethread 8 formed thereon being screwed in a threaded opening 17 of anattaching washer c attached by its claws d to the sole of the shoes 11as shown by dotted lines in FIG. 2. The washer member 5 is providedsymmetrically at both sides of its center with a pair of openings 9 and9, so that a tool having at its top a pair of projections engageablewith the pair of openings 9 and 9, the same can be rotated to be screwedin washer c for being firmly attached.

According to the present invention, the spike member which is liable tobe worn away is made of an abrasion resisting steel while the washermember for attachment is made of a light metal such as aluminum,aluminum alloy or the like, so that'the total weight of the device maybe decreased and may be of sufiicient durability. Additionally, thecombination of the spike member and the washer member is effected by theway the head portion of the spike member is inserted in the cup of thewasher member, and the projecting rim of the spike member is firmlyembraced by the short tube projecting downwardly from the washer member,and by the roll pressing process applied to the outer surface of the cupso that a thread is formed thereon and, simultaneously, the cup ispressed inwardly for causing the inner surface of the same to press intothe uneven surface of the head portion of the spike member. Accordingly,these two members can be very firmly jointed together and excellentproducts can be supplied economically.

What I claim is:

A spike for shoes having a threaded insert adapted to be mounted in thesole thereof comprising a spike member of abrasion resisting steelhaving a tapered end portion, a lateral rim extending from its medialportion and a head portion with an uneven peripheral surface, a washerof a light metal provided at its central portion on one side with anaxially extending cup open at its lower end and an axially extendingshort tube on the side opposite to said cup, said spike member headextending into said washer cup with said cup extending into the unevensurface of said spike member head, said washer short tube embracing saidspike member rim on a side thereof opposite to said spike member headand said washer cup having external peripheral threads for being inthreaded engagement with the threaded insert mountable in the shoe sole.
